Help required setting up home theatre system

prettypennies

I have just bought my hubby a panasonic home theatre system (model no. SC-HT530) to go with our LG LCD TV.

The system has a dvd player 5 speakers and a sub woofer.

When I play discs on the DVD player, the sound comes out of all five speakers. But when the normal TV is on the sound comes out of the front and back left and right speakers but not out of the central speaker. Any ideas why?

TV is only Stereo!

DVDs Have 5 or 6 Audio Channels, creating the surround sound effect.

Stereo is only 2 channels, so you will not get any more than that. The left front audio is most likely the exaclty the same as the left back audio!

At least that's what I think... Sure someone will confirm...

I thought this was the case but as he kept nagging on that it wasn't set up properly I thought I check it out with you more technically minded sorts!

Just a thought.........
Does your TV by any chance have an onscreen setup menu which allows you to switch audio output from stereo/mono etc? Perhaps owners manual or LG support on web might help

If the TV programme sound has been surround sound encoded, it should work. Many adverts, and modern films should work properly, provided that you are using the correct decoding setting on the amp, and everything is plugged in correctly. The rear channels usually have effects/music coming out, not a facsimile of the front speakers, and the central speaker is for speech. It all depends on how it has been processed/mixed by the programme maker.

Hi all,

Hi prettypennies,

Right this can be quite difficult to explain and I should say that I am not a teccy, but I may be able to help you out.

I have a surround sound system, all seperates, purchased from Richer Sounds.

Just about everything I view/listen to on my tv is available in surround sound. The only very rare exception is the odd music video (sky music channels) which is in mono.
You should of course remember that in order for your sound amplifier to distribute surround sound to all the speakers, you need a TV that receives a Nicam stereo signal.

If you have sky, then your sky box does receive a stereo signal.

This stereo signal (received by either your nicam tv or your sky box) is then sent to your amplifier or DVD player which then splits up the sound, and distributes it to the five speakers

From what you have said so far, I am assuming that the system is not wired up/set up properly.

I now need to know if you have sky.
If you do have sky, do you you tend to view the programmes that you watch through the sky box , or do you view terrestrial channels normally.
